The Lowdown
Alright folks, Rusty here. Let’s be straight with you: this 16-day stretch for Kennebunk Beach is a tough one. We’re looking at a long, frustrating wait for any real surf. The water is a touch warmer than normal for this time of year at 67°, but that’s about the only good news.
We’ve got no real swell to speak of for the first week. From Monday, August 31st right through to Sunday, September 6th, it’s a whole lot of nothing. The waves are tiny, the energy is weak, and the conditions are mostly poor. You’ll see a few mornings with clean, glassy conditions early on, but the swell is so small it’s barely worth paddling out for. The energy is low, in the double digits for most of that period, so don’t get your hopes up.
The only real standout in this whole forecast pops up on Sunday, September 6th. Kennebunk Beach is a sheltered spot, and it needs an easterly swell to light up, which is its optimum direction (ENE). The early morning looks promising: a moderate offshore wind from the NE is blowing, which will keep the surf clean. The swell is coming from the ENE at 6 ft, with a period of 8 seconds. The combined energy of all swells directed here is a solid 479, which is a strong shot of energy. This is the best we’ll see, and it’s a good size for intermediates, but the short period means it might be a bit crumbly and not as powerful as you’d like. It’s still the best call in the whole 16 days, but remember, this is a long-range call and things can change.
After that, the swell drops off fast. The rest of the week into September 15th is a write-off. We’re looking at tiny, weak surf with low energy readings (often in the single or double digits), mostly onshore winds, and poor conditions. It’s a long, blank stretch.
So, the word is: if you’re desperate, set your alarm for the morning of Sunday, September 6th, and hope that ENE swell delivers. Otherwise, it’s a long wait for a wave around here.
Rusty, signing off.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
